PYROTECHNIC DEVICE.

SPECIFICATION forming part of Letters Pa n N 7'79,901, dated January 10, 1905.

To on whom it may concern.-

Be it known that I, FREDERIGH T. BECK, a citizen of Switzerland, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and Improved Pyrotechnic Device, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for displaying pyrotechnic or luminous objects, an object being to provide a simple mechanical means whereby a plurality of luminous or burning devices may be rapidly rotated and caused to spread apart by centrifugal action to present practically continuous lines of fire.

I will describe apyrotechnic device embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a pyrotechnic device embodying my invention. Fig. 2 is a plan view thereof. Fig. 3 is a detail showing a form of guide that may be employed. Fig. 4 is a detail perspective view showing a driving-gear and holder employed. Fig. 5 showsamodificationin the holding device, and Fig. 6 is a section on the line 6 6 of Fig. 5.

Referring to the drawings, 1 designates spindles for carrying the illuminating or lightgiving devices, which, as herein shown, consist of Chinese punk 2. It is to be understood, however, that other light-giving devices may be employed-such, for instance, as incandescent lamps, Roman candles, Greek fire, or the like, and of various colors to give a pleasing effect.

I have shown two sets of spindles; but it is obvious that only one set need be employed, or the number may be increased without departing from the spirit of myinvention. As a means for imparting rotary motion to the spindles I employ a mechanical device comprising a gear-wheel 3, mounted on a frame or handle 4: and meshing with a pinion 5, the said pinion 5 engaging with another pinion 6. These pinions are mounted on studs on the end of the frame 4:. Extended eccentrically from each pinion 6 is a stud 7, and on each stud is a socket member 8 for receiving the ends of the spindles.

In Figs. 5 and 6 I have shown a stud 9, which is substantially trough-shaped, and movable over the same is a collar 10 for holding the spindles after placing the same in the trouglrshaped stud.

Forward of the frame are guides for limiting the outer movement of the several spindles, caused by centrifugal action. These guides consist of rings 11, formed on laterally-extended portions of wires 12, attached to the frame 4. Ihave shown the guides, particularly in Fig. 3, as having undulations for causing a varied degree of circles during the rotary movements of the spindles; but the guides may be otherwise shaped to provide for various motions.

It will be noted that the socket members 8 are arranged in such relation to each other that the two sets of illuminating devices will be caused to intertwine somewhat while in rotary motion, and it may be here stated that while I have illustrated and described a specific and simple means for causing the rotary movements I do not confine my invention thereto, as other forms of motors may be employed, and in case of large fireworks it may be necessary to operate the same by electric or similar power.

In the operation as the several spindles are rapidly rotated they will gradually flare outward or separate by centrifugal force,the spindles of course being sufliciently resilient to permit of such spreading movement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a device for the purpose specified, a plurality of spindles for carrying luminiferous material, and means for causing said spindles, while being rotated, to describe irregular lines.

2. In a device for the purpose specified, a plurality of spindles carrying luminiferous material, means for imparting rotary motion to the several spindles, the said spindles being of resilient material, and a guide of irregular interior form for limiting the spreadcarried by the spindles, means for causing rotary movement of the two series of spindles, and means for limiting the spreading motion of the several spindles in the two series.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

FREDERICH T. BECK.
